All HTC phones launched after September 2011 are now 'unlockable' from HTC Developer site

HTC has updated their Developer site's bootloader unlock page, and the news is good:

All HTC Android devices launched after September 2011 are unlockable. The website will be updated accordingly to reflect this in the coming weeks. We continue to work on models launched prior to September 2011, please check back often for the status of older devices.
